Convergent wireless communication system

ABSTRACT

The present invention discloses a global wireless network (convergent box) that can interface with existing telecommunication systems so as to enable the existing telecommuncation systems to handle the increasing demands of wireless communication.

BACKGROUND OF THE INVENTION

[0001] Significant growth in the demand of wireless voice and dataservices, worldwide deregulation in the telecommunication industry, andglobal availability of different frequency licenses are bringing aboutfundamental changes in the wireless telecommunication industry. Thesefundamental changes give rise to new industries such the as WirelessInternet Usage, the Short Message Service (SMS) and the multimediaservices. Due to the rise of these new industries, the wirelessinfrastructure market is poised for explosive growth. Initially, thegrowth will primarily be driven by convergence of cellular phones,personal digital assistance (PDA) and the Internet. There will beincreasing demands for fast data transfers in the forms of voice, audio,and text, either through cellular phones or other mobile equipment. Inaddition, consumers are expected to demand video data over theircellular phones in the immediate future. Even though the existingwireless infrastructure cannot meet these demands, it is neverthelessextremely well poised for low cost upgrades so as to meet these demands.Innovation in the telecommunication industry will bring about tremendouschange in personal lifestyle and ways for people to conduct business.

[0002] Despite of this optimistic outlook, wireless carriers face anumber of challenges with the existing infrastructure as well as thenext generation of wireless infrastructure. The existing infrastructureis unable to meet the demands for high bit rate services. In addition,the existing infrastructure cannot support large volumes of datademanded by mobile and multimedia markets. Customers want to combinemobility with multimedia and hence, demand higher bandwidth and new dataservices. The next generation specifications such as 3G, UMTS, etc. aretargeted toward meeting these demands. This specification will result inan increase in demand for hardware that is both flexible and capable ofhandling multimedia packet data as well as voice data. In short,existing carries face a colossal amount of uncertainty with nextgeneration services, including which path to take and what to do oncethey get there.

[0003] Mobile service providers are looking for a low cost solution thatwould avoid complete overhaul of their equipment so as to protect andgive leverage to their existing investments. A smooth transition to nextgeneration systems is a must for many of these service providers if theywant to maintain their competitive edge.

[0004] In addition, increased competition had resulted in aggressivepricing due to reduced average airtime revenue per subscriber. As anupgrade provider, it is imperative to understands the need to increasedrevenue by attracting new customers, encouraging subscriber MOU(minutes-of-use) growth, and deploying value-added, revenue-generatingfeatures such as unified messaging and network-based intelligent agents,as well as support for data applications.

SUMMARY OF THE INVENTION

[0005] The present invention has the flexibility to provide service toVoice and Data to traditional PSTN and IP backbone networks. Thedistributed architecture system is easily scaleable for small to largedeployment for wireless carriers. The architecture deliversinteroperability between core network and external networks with supportof many protocols including TCAP, MCAP, MAP, SS7, Q.931, MGCP, SIP,(FEED MORE PROTOCOLS).

DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0020]FIG. 1 illustrates a diagrammatic view of the relationship betweenthe present invention and a first communication system environment. Thepresent invention is the convergent Box 100. In this communicationsystem environment, there is a based transceiver station (BTS) 102, abase station controller (BSC) 104, a mobile switching center (MSC) 106,a visitor location register (VLR) 108, a home location register (HLR)110, a public switched telephone network (PSTN) 112, an Internet 114, aglobal system for mobile communications and generalized packet radioservice (GSM-GPRS) 116, a time division multiple access (TDMA) 118, awide code division multiple access (WCDMA) 120, and an operationmaintenance center (OMC) 122. The convergent box is interconnected withthese various systems as shown by the representative connections. Theconvergent box supports multiple carrier frequencies like those for GSM,TDMA, WCDMA-2000 networks. The convergent box also supports voice anddata services not only limited to GSM to GSM global network access, butalso to GSM to WCDMA global network access. Carriers can configure theconvergent box according to their frequency licenses and their businesspartnership with competitors to access other networks. Besidessupporting basic voice and data services, the convergent box alsosupports call controls, registration, roaming for voice and data,billing, internal as well as external operability amongst variousnetworks. The convergent box is able to interface with most wirelesselement and the box is scalable from both hardware and softwareperspectives.

[0021] The Base Transceiver Station (BTS) 102 contains Radio Frequencycarriers to handle various frequency ranges. It is able to transmit toand receive from signal of a cellular subscriber. The Base StationController (BSC) 104 provides interface between BTS 102 and MSC 106 toprovide call controls and management. BSC 104 is also connected tomultiple other BTSs. The Mobile Switching Center (MSC) 106 is atelephone switching exchange to handle mobile subscriber traffic,including both originating and termination. The Visitor LocationRegister (VLR) 108 is a subscriber database, which is dynamicallyproviding help for roaming features such as temporary access to othernetwork. The Home Location Register (HLR) 110 is also a subscriberdatabase. It is a static and master database. Its function is to provideassistance to registration and verification processes.

[0022]FIG. 2 illustrates a diagrammatic view of the relationship betweenthe present invention and a second communication system environment.This environment includes a pair of cellular devices in wirelessconnection with a network 202 including a CDMA, TDMA, GSM with extendedcoverage for BTS, BSC, and RAN. The environment also includes a MSC 204,a PSTN 206, a convergent box 208, a broadband network 210 a PLMN network212, a GPRS network 214 with GSM and TDMA, an CDMA network 216, a PLMNnetwork 218, and an IMT 2000 220. As shown, the convergent box 208 iscentrally interconnected with the various networks.

[0023]FIG. 3 illustrates a diagrammatic view of a protocol stack of thepresent invention. Base transceivers 302 interface between variouswireless devices and base stations 304. The base stations 304 serve asinterfaces with a cluster of software protocol stack 320. The stack 320encompasses a group 306 comprising transaction capabilities applicationpart (TCAP), and a mobile application part (MAP); a group 308 comprisinga base station system management application part (BSSMAP), and ageneral packet radio services mobility management (GPRSGMM); a group 310comprising a H.323, media gateway control protocol (MGCP), a sessioninitiation protocol (SIP), a SS7, and a Q.931; and a group 312comprising a message transfer part layer 1 (MTP1), a message transferpart layer 2 (MTP2), a base station system management application part(BSSMAP), an internet protocol (IP), and an asynchronous transfer mode(ATM). The group 306, group 308, group 310 and group 312 caninteractively communicate with each other. The stack 320 can alsointeractively communicate with a Global wireless Network 300, a MSC 316,a soft switch 318 and an external network 314.

[0024]FIG. 4 illustrates a flow chart diagram explaining the systemlogic flow of the present invention. The diagram as a whole shows twomain branches, a primary wireless network, and a convergent servicenetwork. Whenever a subscriber is unable to access a primary wirelessnetwork, the convergent service network will be made available. When asubscriber initiates a service request via a wireless device, as shownin step 400, a wireless contact is made with a base transceiver station(BTS), as shown in step 402. A determination is made on whether therequested service should be fulfilled by the primary wireless network498 or the convergent service network 499. The determination could bebased on network availability, resources needed to fulfill the requestedservice, preferences indicated by the subscriber, cost differentialanalysis based on the services requested, among other factors, as shownin step 404. Should it be determined that the convergent service networkis needed, the service requested will be fulfilled by the convergentservice network 499. As shown in steps 600 and 602 in FIG. 6, allservice requests thereof will be processed under procedures within theconvergent service network 499.

[0025] Should it be determined that the service request should behandled by the primary wireless network 498 at step 404, a base stationcard (BSC) will decide based on the service request whether it should befulfilled by a circuit or a packet switched network. A PSTN network maybe chosen to provide a fast access, or a PLMN may be chosen for a widebandwidth, as shown in step 406. A determination will then be madewhether the service request requires a voice network or a data network,as shown in step 408. If a data network is required, a proper bandwidthwill be allocated, as shown in step 410. Thereafter, a determination ismade on whether a proper amount of bandwidth is available, as shown instep 412. If a proper amount of bandwidth is available, a callingprocess will be initiated, as shown in steps 414 and 416. At whichpoint, a determination is made on whether the calling process issuccessful, as shown in step 500. If yes, then proper resources will beallocated as shown in step 502 and the calling process will be carriedto fruition, as shown in steps 504 and 506. Should it be determined thata calling process is not successful, then the convergent service network498 will be chosen to provide the requested service until fruition, asshown in steps 508, 510 and 512. Regardless of which network providesthe requested service, at the conclusion of a call, billing records willbe kept, as shown in steps 418, 420 and 422.

[0026] Should it be determined at step 412 that there is insufficientamount of bandwidth, then a borrowed service will be utilized, as shownin step 424. Typically but not always, borrowed services are needed whena killer application is encountered. Borrowed services will be providedby a carrier with a similar cost structure, as long as the contactedcarrier is able to fulfill the demands of the requested service.Borrowed services will likely be handled by a 3G or an IMT2000 basednetwork with access to PLMN and Internet via high speed switches,gateways and fiber optic backbone networks. A calling process will beinitiated as shown in steps 426 and 428. Steps 500, 502, 504, 506, 508,510 and 512 in FIG. 5 will be employed. At the conclusion of a call,billing record will be kept, as shown in steps 430, 432 and 434.

[0027] Should it be determined at step 408 that a voice service isdesired, then a further determination is made on whether the servicerequest should be handled by a PSTN or an Internet, as shown in step436. If PSTN network, then a calling process will be initiated untilfruition followed with a recordation of billing record, as shown insteps 438, 440, 442, 444, 446 and 448. If Internet, then a callingprocess will be initiated until fruition followed with a recordation ofbilling record, as shown in steps 436, 450, 452, 456, 458, 460 and 462.During the call in progress at step 456, it is possible that morebandwidth is needed. More bandwidth may be allocated, as shown in step604. If the bandwidth is successfully allocated, then the servicerequest is provided until fruition, as shown in steps 606, 608, 610 and612. If the proper amount of bandwidth is not successfully allocated,then the convergent service network is employed, as shown in steps 614,600, 602 and 616.

[0028]FIG. 7 illustrates a high speed-processing card (HSProc) of thepresent invention. This card may interactively communicate with localarea networks, Ethernet, among others. Contained therein the card is aregister ports module 700, a parallel port module 702, a dual processormodule 704, a timer 706, a memory 708, a serial port interface module710 with an optical isolator 712, a GSM module 713, a TDMA module 714, aCDMA module 716, an arbitary bus module 718, a communication processormodule 720, a MCAP 722, a LAPD processor 724, a TDM interface controller726, a LAN Controller module 728, an interface controller 730, a GigabitEthernet 732, a fiber optics controller 734 and a graphic controller736.

[0029]FIG. 8 illustrates details of a convergent box of the presentinvention. As shown, the box is configured to house various cards. Byway of an example, two control cards 814 and 816, a WAP card 813, abroadband card 812, a TDMA card 810, a PSTN card, a Billing card 806, aWCDMA card 804 and a GPRS card 802 are installed. The convergent Box isdesigned by standards conforming to that of 3GPP, 3GPP2 and IMT 2000.Regarding GPRS 802, WCDMA 804 and TDMA 810 cards, interface will provideconnectivity to incoming traffic from BTSs/Radio Network or BSCs andexternal network beyond wireless networks. Interface support featuresinclude voice, data and multimedia applications. These cards possessfeatures like call processing, mobility management and resourcemanagement of channels (voice and data). All connections will establishend-to-end IP connectivity through gateways, routers to legacy networksby T1/E1, Frame Relay, OC-3, OC-12 interface. Each card will havedifferent kinds of ports and custom configured to fit various networks.

[0030] Regarding billing card 806, for every call and every access tonetwork, this interface will generate report for every connection thathas been established, software from a 3^(rd) party may be integrated.

[0031] Regarding connectivity with PSTN card, this card supportscircuit-switched data for voice, especially for 2G network. Ifsubscribers and carriers are capable to handle data, then service can bemade available via software features, gateways and soft switchintegration from certified vendors.

[0032] Regarding the support of current WAP based network, these cardswill support all data calls, and upcoming WAP based applications.

[0033] Regarding control cards 814 and 816, traffic shaping, analyzingcontrol are all managed by software and most of incoming and outgoingtraffic can be monitored by these cards.

[0034]FIG. 9 illustrates an information flow diagram of a communicationsystem depicting a voice call from a first mobile subscriber to a secondmobile subscriber. As shown, the information flow diagram is between thefirst mobile subscriber MS1, the second mobile subscriber MS2, the basetransceiver station BTS, the base station controller BSC, the firstmobile switching center MSC1 and the second mobile center MSC2.

[0035] MS1 initiates a random access for a channel at step 1. Dependingupon whether a priority is given to the strength of a signal, proximitybetween MS1 and BTS, pre-arranged assignment based on service region, orother factors, one BTS among many acknowledges and decides to respond tothe random access request. Along with the random access request, achannel request is also sought after by MS1, as shown in step 2. Inresponse thereto, BTS assigns a channel to MS1 as shown in step 3. MS1then makes a checking request to BSC via BTS, as shown in steps 4 and 5.The checking requests for information regarding subscriber information,bandwidth, channel, etc. that was prearranged for MS1. Possessed withthe relevant requested information, BSC provides the relevant requestedinformation to BTS, as shown in step 6. BTS then immediately assigns achannel commensurate with the prearrange setup to MS1, as shown in step7.

[0036] At step 8, BTS initiates a layer 3 information call managementservice request to BSC. This request will initiate various types ofprearranged activities such as establishing links, call processing, settimer, set events, MTP, etc. A call handle will be initiated from BSC toMSC1, as shown in step 9. Based on the telephone number dialed by MS1, adestination will be determined. In conjunction with other intelligentprocesses which is not shown in this diagram, a proper MSC2 will beginto search and make contact with MSC1, as shown in step 10. MSC2 willprompt for incoming call with assigned channel to MS2, as shown in step11. Thereafter, a voice channel is assigned by BSC to each of MS1 andMS2, as shown in steps 12 and 13. At step 14, an acknowledgement toindicate that MS2 is within range is extended to MSC1 from MS2. A callestablishment between each of MS1 and MS2 is completed, as shown insteps 15 and 16. MS1 and MS2 can effectively communicate with eachother. Once the communication is completed, MS1 and MS2 will eachseparately inform BSC of call completion and release the assignedchannel, as shown in steps 17 and 18. Release of resources and separaterecording of billing information will be done in steps 19 and 20.

[0037]FIG. 10 illustrates an information flow diagram of a communicationsystem depicting a voice and data call from a first mobile subscriber toa second mobile subscriber over either a 2G or a 3G switch of thepresent invention. As shown, the invention flow diagram depictsinteractions between a first mobile subscriber MS1, a second mobilesubscriber MS2, a base transceiver station BTS, a base stationcontroller BSC, a first mobile switching center MSC1, a second mobileswitching center MSC2, and a data network DN. As depicted in thisdiagram, a voice connection between MS1 and MS2 is made first. Shouldthe need arise, a data connection between MS1 and MS2 is made later.

[0038] At step 1, a random access attempt to reach a channel is made byMS1. Typically, either a BTS closest to MS1 or a BTS receives thestrongest signal from MS1 acknowledges the random access attempt. TheBTS that acknowledges the random access attempt also acknowledges achannel request of MS1, as shown in step 2. In response to the channelrequest, a channel is assigned by BTS to MS1, as shown in step 3. Forthe purpose of enabling BSC to provide proper control and management toBTS and MSC, a checking request is made by MS1 to BSC, as shown in step4. The type of control and management commensurate with apre-arrangement is immediately assigned to MS1 by BTS, as shown in step5. For high level controls, a layer 3 information call managementservice request for a complete layer 3 process is initiated from BTS toBSC, as shown in step 6. A call handle is then provided by BSC toMSC1/SS, as shown in step 7. Based on the telephone number dial andother intelligent feature, a proper MSC2/SS makes a search from MSC2/SSto BSC, as shown in step 8, then MSC1/SS makes a prompt for incomingcall with assigned to MS2, as shown in step 9. BSC follows with making aseparate voice channel assignment to MS1 and MS2, as shown in steps 10and 11. MS2 will also make an acknowledgement that MS2/SS is withinrange. MS1 and MS2 can then intercommunicate with each other, as shownin steps 12 and 12 a.

[0039] Anytime during the voice communication, out of necessity, MS1initiates a data request service with BTS, as shown in step 13. Inresponse to the data service request, BTS hunts for proper bandwidth andavailable reserve channel from BSC, as shown in step 14. BSC verifieswith MSCL/SS the need of a data service, as shown in step 15. BSCproceeds with an access to the DN, as shown in step 16. DN confirms withaccess and validation such as identification, password,network-provisioning etc. with BSC, as shown in step 17. BSC proceeds tofeed a data channel to MS1, and MS1 directly access DN, as shown insteps 18 and 19. MS1 continues by making a request to obtainconnectivity with MS2 to BSC, as shown in step 20. BSC in turn initiatesa MS2 data request verification to MSC2/SS as well as access to DN andprovide verification for MS2, as shown in steps 21 and 22. In turn DNconfirms with access and validation with BSC, as shown in step 23.Thereafter, BSC feeds a data channel to MS2, as shown in step 24. MS1and MS2 separately make acknowledgement for a successful data connectionto BSC, as shown in steps 25 and 26. MS2 makes a direct connection withDN, as shown in step 27. MS1 and MS2 can then intercommunicate with eachother, as shown in steps 28 and 29.

[0040] When MS1 and MS2 are finished in their communication, they mayseparately inform BSC so that termination procedure may follow, as shownin steps 30 and 31. BSC will separately release all resources toMSC1/SS, MSC2/SS and DN, as shown in steps 32, 33 and 34. MS1 willcomplete billing process for voice and data calls with MSC1/SS and DN,as shown in steps 35 and 37. MS2 will also complete billing process forvoice and data calls with MSC2/SS and DN, as shown in steps 36 and 38.

[0041]FIG. 11 illustrates an information flow diagram of a communicationsystem depicting a simultaneously voice and data call from a firstmobile subscriber to a second mobile subscriber. This is an embodimentwith one channel that supports both voice and data. As shown in step 1,a first mobile subscriber (MS1) initiates a voice and data servicerequest to a base transceiver station/radio access network (DTS/RAN).Upon receiving the request, the BTS/RAN contacts a base stationcontroller (BSC) for the purpose of determining the service plan the MS1has enrolled into, as shown in step 2. The BTS/RAN also informs MS1 thatthe service request has been received, as shown in step 3. The BSC makescontact with a data network (NT) in preparation to provide service toMS1, as shown in step 4. Once protocols are established, the datanetwork informs BSC that connection is established, as shown in step 5.The BSC then assigns a channel with services commensurate with theenrolled service plan to MS1, as shown in step 6. Thereafter, MS1 and DNmay intercommunicate with each other with full capability of voice anddata, as shown in steps 7 and 8. However, due to the fact that a secondmobile subscriber (MS2) has not yet been contacted, intercommunicationbetween MS1 and DN will most likely be with data only.

[0042] A voice call alert is initiated from MS1 to BSC to determine thewhereabouts of MS2 from a mobile network, as shown in step 9. The searchfor MS2 is confirmed with a home location register (HLR), as the BSCcommunicates with a first mobile switching center/soft switch (MSC1/SS),as shown in step 10. MSC1/SS contacts DN in preparation of providingservice to MS2, as shown in step 11. DN then communicates with BSC toallocate voice service to MS2, as shown in step 12. NSC then alerts MSCwith an incoming call, as shown in step 13. After MS1 and MS2 bothcommunicate with BSC, BSC communicates with DN, as shown in steps 14,15, 16 and 17. MS1 and MS2 will then be able to communicate with eachother, as shown in steps 18 and 19. Voice communication will also takeplace between MS1 and MS2, as shown in steps 20, 21, 22, 23 and 24. Ascalls and data exchanges are completed, both MS1 and MS2 inform the BSC,as shown in steps 25 and 26. BSC in turn releases all resources, asshown in steps 27 and 28. Billing records will be kept for voice anddata communication of MS1 and MS2, as shown in steps 29, 30, 31 and 32.

[0043]FIG. 12 illustrates an information flow diagram a communicationsystem depicting a data call communication between a first mobilesubscriber (MS1) and a data network (DN). This could be a situationwhere a wireless device is used to gain access to an internet. Eventhough there is no voice communication between MS1 and MS2 as depictedin FIG. 11, there is still both voice and data services. This setupwould allow MS1 to access, for example, internet email and voice mail.As shown in step 1, MS1 initiates a data call request to a BTS/RAN. TheNTS/RAN in turn contacts BSC to check the enrolled service plan of MS1,as shown in step 2. BTS/RAN acknowledges to MS1 that the request hasbeen received and is being processed, as shown in step 3. Meanwhile, BSCcontacts DN in preparation of providing service to MS1, as shown in step4. Upon successful protocol communication, DN informs BSC, as shown instep 5. BSC then assigns a channel with a requisite bandwidth to MS1, asshown in step 6. MS1 and DN can intercommunicate with each other, asshown in steps 7 and 8. Upon completion of all communications, MS1informs BSC, as shown in step 9. BSC then releases all resources for theconnection to DN, as shown in step 10. Billing records for the servicewill be kept, as shown in step 12.

[0044]FIG. 13 illustrates a network diagram showing various connectivityrelationships over voice and data calls. This network diagram includes apair of mobile subscriber devices 1300, a BTS (CDMA) 1302, a PSTN 1304,a BTS (TDMA) 1306, a BSC 1308, a MSC 1310, a telephone 1312, a network1314, an OMC 1316, a global wireless network (GWN) 1318, a WCDMA/CDMA2000 network 1320, a GPRS network 1322 and an Internet 1324. They areinterconnected via voice connectivity, data connectivity and interfaceto other network as shown.

[0045] In order to support 2.5G GPRS network 1322 and Enhanced GPRS(EGPRS) network for 3G wireless systems, changes are required within theBSC 1308, and other wireless network elements like MSC 1310 and externalnetwork. A new packet control unit (PCU) that directs the data trafficto the GPRS network 1322 or the EGPRS network is required. GWN 1318develops a next generation BSC module 1308 which has an integrated PCU.The data traffic will be forwarded to the GPRS network 1322 or the EGPRSnetwork via another network element (GWN box) with the followingfeatures:

[0046] A next generation BSC module with an integrated PCU.

[0047] A GWN network element (GWN box aka convergent box) whichinterfaces to the new BSC and the GPRS network or the EGPRS network.

[0048] Initially, the GWN Box offers services to Class A terminals ofGPRS networks. Subquent GWN Box will support all classes of 2.5G GPRSterminals and 3G wireless terminals.

[0049] The next generation BSC with the integrated PCU interfaces withthe GWN network element via high speed link(s) such as frame relay andATM interface. Another key feature is a support of simulataneous voiceand data multiplexing within the same session. This is accomplished withsmart built-in GWN software algorithm along with PCU hardware, to allowboth voice and data session to co-exist independent of each other. Thus,providing the required support for the next generation GPRS terminalsthat with the capabilities to send voice and data trafficsimultaneously.

[0050] One important aspect of consideration here is the support formultiple air interface standards. The support for mutiple air interfacestandards can also be built within this new BSC. As we can see thisdetermination and decision for multiple air interface standards will bebased on existing BSC infrastructure, marketing objectives, and variouscost factors thereby allowing for smooth migration to 2.5G GPRS systemand to 3G systems.

[0051] Although BSC products for 2.5G GPRS and for 3G wireless systemsare available from several major wireless suppliers, these products areusually designed for a specific air interface standard and a specificcore network. The main reason for using the GWN box is scalability toprovide support for multiple air interface standards and multiple corenetwork architectures. It will facilitate data traffic forwarding to2.5G GPRS network, 3G EGPRS network for WCDMA and Enhanced Mobile IPnetwork for CDMA2000. The GWN supports interfaces to the GPRS network(2.5G or 3G). Modules can be added to interface with Enhanced Mobile IPnetwork for CDMA2000, and Enhanced GPRS network for WCDMA. The GWNnetwork element is a scalable box which will terminate multipleinterfaces from the various BSC modules. It supports the termination ofthe existing BSCs (if required) and the next generation GWN BSC modules.

[0052] GWN's BSC module and GWN box supports the GPRS TunnelingProtocols to ensure the security to data network and circuit switchnetwork. GWN network element will also provide secured and virtualconnection to other WCDMA network or CDMA2000 network. GWN box havecards for 3G EDGE-TDMA and capable to have access to 2G ANSI TDMA, WCDMAand CDMA2000 to provide packet data service to core networks andinterface with base stations. The GWN network element will provideinterface to the 2.5G GPRS network or 3G EGPRS network (or EnhancedMobile IP network if GWN wants to support cdma2000).

[0053]FIG. 14 illustrates a reference model of a SPRS network with SGSNand GGSN by Cisco. This figure shows the interfaces 1, 2 and 3connections to PSTN networks for voice call and interfaces 4,5 and 6 forcircuit-switched data calls. These capabilities are managed in BSC withsoftware call controls that enable more bandwidth, support for multipleair interfaces from BTSs, and connects to suitable reference point ofSGSN element of GPRS network or EGPRS network through GWN box.Interfaces 7, 8 and 9 adds more flexibility, scalability,interoprability, roaming to GPRS network or WCDMA-EGPRS network orCDMA2000 nework. An important characterstic of this architectural viewis the migration from circuit-switched network to packet-switchednetwork.

[0054] From the foregoing detailed description, it will be evident thatthere are a number of changes, adaptations and modifications of thepresent invention which come within the province of those persons havingordinary skill in the art to which the aforementioned inventionpertains.
